Thanks, Ray. Here is some more info.

Yes I can run a web browser and surf the net through the router from the same
win95 client that failed with Eudora. I am not familiar with telnet and
have not had
to check it out yet.

I can neither send or check mail through the router using Eudora. Not while
the modem
is attached to the router; not even when I move the modem to the win95
client and directly
dialing-up the ISP. In the latter situation I had to "Disable DNS" in the
windows95 network
configuration to check and send mail again. Disabling DNS removes the
nameservers of
the ISP from the win95 client networking config; the same sets of numbers
from /etc/resolv.conf

I use POP3. My kernel is 2.0.34, Slackware 3.5. My firewall settings are as
follows:
in /etc/rc.d/rc.local
ipfwadm -F -p deny
ifpwadm -F -a m -S  <ip.number.of.client1>/32 -D 0.0.0.0/0
ifpwadm -F -a m -S  <ip.number.of.client2>/32 -D 0.0.0.0/0
.......client3 et cetera
------------------
in /etc/rc.d/rc.modues
/sbin/modprobe ip_masq_ftp

That is very encouraging. Knowing that it can be done.

Yes I have TCP/IP bound to both Dial-Up Adaptor and Ethernet adapter.

I seem to have done everything but have not gotten it right yet!!

Not yet giving up,
